TUBE-CLEANER GUIDE AND NOZZLE.

Specification of Letters Patent.

Application filed December 15, 1911. Serial No. 665,956.

To all whom it may concern Be it known that I, CHARLES F. OVERLY, a citizen of-the United States, residing at Pittsburgh, in the county of Allegheny and State, of Pennsylvania, have invented certain new and useful Improvements inTube- Cleaner Guides and Nozzles, of which the following. is a specification, reference being had therein to the accompanying drawings.

My invention relates to tube cleaning devices and more particularly to a device for supplying water to the tube while the tube cleaner is at work.

In operating tube cleaners by other than water driven motors it is desirable to introduce a supply of water, and the object of my invention is to provide simple and efiicient means for this purpose conveniently arranged for the guidance and easy handling of the cleaner.

With these and other objects in view my invention consists of the constructions and combinations hereinafter described and set forth in the claims.

In the drawings Figure 1 is a sectional view of a device embodying my invention, shown attached to the header of a water tube boiler, Fig. 2 is a front view of the.

same, Fig. 3 is a longitudinal section of the device, and Fig. 4 is a cross-section on the line 4-'l of Fig. 3.

Like numerals represent the same figures in the several views.

cleaner through the header into the tubes.-

The portion 5 of the device ismade hollow forming a chamber 6 having a screw-threaded opening 7 to secure a supply conduit 8. A plurality of ports 9 extend from the chamber 6 through the wall of the inwardly projecting portion 10 of the device and disv charge into the tube to be cleaned. The

channel or guide-way 10 extends through the upper portion of the device so that a cleaner head or a cleaner head and its motor, where a motor is employed that is adapted to travel through the tube with the cleaner, can be introduced through the outer end of the channel and be guided thereby into the tube that is in alinement with the circular opening in the header in which the device is secured; and further it will be seen the construction is such that a cleaner head or a cleaner head and its motor can be withdrawn through the device while in its fixed position in the header opening.

The device is easily secured in place by simply introducing the inwardly projecting portion 10 through the opening 4 in the header with the portion 5 abutting the outside of the header, then dropping it into position with the flange 11 abutting the inner side of the header as shown. a i

It will be seen that by making the device substantially are shaped in cross-section it is adapted to fit snugly in the circular opening in the header and give the greatest possible clearance for the passage of the tube cleaner through the opening in the head; and further that the means of securing the device to the header is very simple, the portion 5 of the body resting against one side Patented Jan. 12, 1915.

of the header and the flange 11 projecting a from the portion 10 of the device engaging vice can be readily removed from one opening to another in the header.

The device may be used with a single nozzle but I'preferably employ a plurality of nozzles as shown.

Having thus described my invention I claim A device for the purpose set forth, comprising a casting having an end portion with achamber therein and an extension with a flange on its under side; the upper portion of said casting and extension having a channel with curved walls, and said extension having a passage or passages leading from said chamber to the free end of said extension.

In testimony whereof I have hereunto affixed my signature in the presence of two witnesses.
